Vicki Gunvalson has shut down Kill All Cancer three weeks after it was announced that she joined forces with a longtime friend to start the cancer charity.

“I just shut it down because there was a lot of naysayers out there,” Gunvalson, 54, told Entertainment Tonight. “I’m not going to do something that’s going to be criticized when I did it from a good place. And it wasn’t my charity. I was just a spokesperson for it. So it wasn’t mine.”

On the Sept. 26 episode of RHOC, Gunvalson said of joining the charity, “Cancer obviously was very relevant in my life last year. People tried to label me as in on a whole fake cancer scheme. What are they going to do? Criticize me for opening a charity to try and help find a cure?” She continued: “Working with a cancer charity will prove the naysayers out there who said I was in on something or that I lied that I’ve got nothing to hide. Period.”

The charity was also set up to have an insurance component built behind it as well. Gunvalson, who is already a successful insurance saleswoman, said on RHOC: “This ‘Kill All Cancer’ policy will be something people will buy, and then if they ever got sick, this will help people get back on their feet again. This is up my wheelhouse – I’m all about insurance, I’m all about charities, so I’m all in.”
